Sinister Diesel - Tuners & Programmers

If you’ve been looking for more power from your Cummins, Powerstroke, or Duramax-powered diesel but don’t want to spend the time or money to have an engine professionally built, pick up one of the easy plug-in diesel tuners from Sinister Diesel.

Plug-In Diesel Tuners from Sinister Diesel

With modern, computer-controlled diesel engines, it’s easier than ever to unleash instant performance from your stock components. The engine that came in your truck is always capable of producing more power than the factory tuning allows, and you can free your engine in just a few minutes with just basic tools!
Diesel tuners, including chips, modules, and programmers, all work by modifying the stock engine parameters like injector pulse width, boost pressure, and fuel rail pressure, getting more fuel into the engine when it needs it. You’ll get an expanded powerband, fewer downshifts, more efficient combustion, and better fuel economy. Not only is your truck going to be stronger and more enjoyable to drive, it’ll be more efficient which saves you money in fuel costs!
